Embodiment Construction

[0088] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0089] see figure 1 As shown, the rear view reversing assistance system in the present invention includes a video collector, an image synchronization processor, a DSP processor, a logic controller, a storage module, an output frame buffer, a video decoder, a video display and an audio alarm. The video collector, image synchronization processor, DSP processor, output frame buffer, video decoder and video display are connected in sequence, and the logic controller is connected to the image synchronization processor, DSP processor, output frame buffer, video decoder and audio alarm , the DSP processor is connected to the storage module; the video collector includes two pinhole cameras, which are fixed and installed on both sides of the rear outer surface of the car in parallel, and the images of the two cameras must overlap to a certain extent. The storage modul...

Abstract

The invention discloses a rearview reversing auxiliary system and a method for forming rearview obstacle images. The method belongs to a method for carrying out automatic identification, distance measurement and final fusion display on obstacles in rearview scenes during the vehicle reversing on the basis that the outer surface of two sides of the back of a vehicle are fixedly and parallelly provided with two cameras. The method sequentially comprises three parts including cutting, distance measurement and fusion, wherein the cutting part comprises pretreatment, self-adaption FCM (fuzzy C-means) cutting and treatment after cutting, the distance measurement part comprises SIFT (scale invariant feature transform) feature matching, camera calibration and distance measurement, the fusion part mainly builds correlation rules and carries out fusion display by combining practical traffic scene conditions according to the measured distance information. The method has the advantages that the vision blind region of the vehicle back is eliminated, obstacles in the rearview images are automatically divided, in addition, the distance from the obstacles to the vehicle is obtained, the fusion display of most urgently concerned obstacles with the nearest distance during the reversing is realized, and the interference of other objects in remote distance is eliminated, so the reversing is more convenient and fast.

Description

【Technical field】 [0001] The invention belongs to the technical field of reversing images, and in particular relates to a rear view reversing assistance system and a method for automatically identifying, measuring and fused displaying obstacles in the rear field of view when the vehicle is reversing. 【Background technique】 [0002] With the rapid prosperity and development of the automotive electronics market, the traditional parking assist system has been replaced by a visual parking assistance system. The popular rearview camera backup system in the market is to install a camera at the rear of the car. When the driver starts reversing, the camera captures the rear view scene in real time and transmits it to the display of the car center console, so that the driver can intuitively understand the situation behind the car, and it is safer and more convenient to reversing. However, installing only one camera at the rear of the car can only cover a limited area behind the car, ...
